An Oconomowoc man died when his car rolled over and burst into flames after it slid out of control at about 10 p.m. Jan. 12 in Dodge County, police said.

According to the Dodge County Sheriff's Office, the man, 56-year-old Patrick J. Clark, lost control of his 2001 Mercedes Benz E while negotiating a curve on eastbound Highway MM just west of Highway EM in the town of Emmet.

The car slid counterclockwise into a nearby ditch, where it collided with a culvert, flipped, landed upside down in a driveway and burst into flames, according to a Jan. 17 news release.

The sheriff's office said a passing motorist saw the crash and tried unsuccessfully to pull Clark from his vehicle. Clark was pronounced dead at the scene.

Investigators believe speed was a factor in the crash, the sheriff's office said Jan. 18. Slick roads did not play a role.
